FIG. 1A-1C are partial schematic view showing planar structures of asubstrate provided with a plurality of holes. As illustrated in FIG. 1A,a substrate 10 is provided with a plurality of holes 11 arranged in theX direction and the Y direction, and the holes 11 penetrate through thesubstrate 10 in a direction perpendicular to the substrate 10. FIGS.1A-1C are described with an example of applying a force parallel to theX direction to the substrate 10 to bend or stretch the substrate 10.When a force as illustrated by an arrow in FIG. 1A is applied to thesubstrate 10, the holes 11 in the substrate 10 are limited by thenon-hole region, so the holes 11 cannot provide deformation effectively,and the cross section of the substrate 10 in the force applicationdirection is reduced due to the presence of the holes 11, so thesubstrate 10 is prone to fracture.

As illustrated in FIG. 1B, the substrate 10 is provided with a pluralityof holes 11 arranged in a plurality of rows in the Y direction, theholes 11 of adjacent rows are offset from each other in the X direction,and the edge of the first row of holes 11 adjacent to the second row ofholes is located on the same straight line as the edge of the second rowof holes adjacent to the first row of holes. When the force applied tothe substrate 10 is as illustrated by the arrow in FIG. 1B, the holes 11in the substrate 10 are limited by the non-hole region, so the holes 11cannot provide deformation effectively, and the substrate 10 cannotprovide a degree of deformation greater than the materialcharacteristics thereof, thus the substrate 10 is prone to fracture.

As illustrated in FIG. 1C, the substrate 10 is provided with a pluralityof holes 11 arranged in a plurality of rows in the Y direction, theholes 11 of adjacent rows are offset from each other in the X direction,and the holes 11 of adjacent rows overlap in the Y direction. When theforce applied to the substrate 10 is as illustrated by the arrow in FIG.1C, the force passes through the holes 11, and the holes 11 can provideeffective deformation. The strain generated by the substrate 10 isgreater than the strain generated when the substrate 10 is not providedwith the holes. Thus, the substrate 10 has better stretchability whensubjected to the force illustrated in FIG. 1C.

FIGS. 1D-1E are partial schematic views showing planar structures ofother substrates provided with a plurality of holes. In FIGS. 1D-1E,when a force parallel to the X direction is applied to the substrate 10,at least some holes 11 exist in the direction of the force application.However, when a force in other directions is applied to the substrate10, none of the holes 11 may exist in the direction of the forceapplication (as illustrated by arrows in FIGS. 1D and 1E). At this time,the substrate 10 cannot provide a degree of deformation greater than thematerial characteristics thereof, and the substrate 10 is prone tofracture.

In the research, the inventor of this application found that the displaydevice needs to be stretchable in all directions. Therefore, how todesign a display substrate with stretchability in all directions hasattracted extensive attention.

Embodiments of the present disclosure provide a substrate and a displaydevice. The substrate provided by embodiments of the present disclosureincludes a hole region which includes a plurality of holes penetratingthe substrate; and a non-hole region including a plurality of connectionportions and a plurality of pixel regions separated from each other,each connection portion being located between adjacent pixel regions toconnect the adjacent pixel regions. A straight line with any directionparallel to the substrate passes through the hole region. The substrateprovided by embodiments of the present disclosure can satisfy therequirement that the substrate has stretchability in any directionparallel to the substrate, and the substrate can be manufactured byusing an existing process, and the process is simple.

The substrate and the display device provided by embodiments of thepresent disclosure will be described below with reference to theaccompanying drawings.

FIG. 2A is a partial schematic view showing a planar structure of asubstrate according to an embodiment of the present disclosure. Asillustrated in FIG. 2A, the substrate 100 includes a hole region 1100including a plurality of holes 110 penetrating the substrate 100 in adirection perpendicular to the substrate 100; and a non-hole region 120.The non-hole region 120 includes a plurality of connection portions 121and a plurality of pixel regions 122 separated from each other, and eachconnection portion 121 is located between adjacent pixel regions 122 toconnect the adjacent pixel regions 122. The above-mentioned “a pluralityof pixel regions separated from each other” means that although adjacentpixel regions 122 can be connected by the connection portion 121, theadjacent pixel regions 122 are spaced apart and independent of eachother. As illustrated in FIG. 2A, a straight line 200 with any directionparallel to the substrate 100 passes through the hole region 1100, thatis, when a force parallel to any direction of the substrate 100 isapplied to the substrate 100, the direction of force application passesthrough at least one hole 110. At this time, in the direction of forceapplication, the strain generated by the substrate 100 is greater thanthe strain that can be generated when the substrate 100 has no hole,that is, the substrate 100 generates a degree of deformation greaterthan the material characteristics thereof. That is, the continuoussurface on which the force applied to the substrate 100 is transmittedis non-linear so that the substrate 100 can be stretchable. Therefore,the substrate provided by the embodiment of the present disclosure cansatisfy the requirement that the substrate has stretchability in anydirection parallel to the substrate.

For example, as illustrated in FIG. 2A, a closed region surrounded by aplurality of pixel regions 122 adjacent to each other and connectionportions 121 connecting the plurality of pixel regions 122 adjacent toeach other is the hole region 1100.

For example, as illustrated in FIG. 2A, four adjacent pixel regions 122are respectively located at the four vertices of the quadrangle 1200,the connection portions 121 connecting the four pixel regions 122 arerespectively located on the four sides of the quadrangle 1200, and theclosed region surrounded by the four pixel regions 122 and the fourconnection portions 121 is an hole 110 included in the hole region 1100.

It should be noted that the “pixel region” here is only to illustrate aplurality of separate specific regions on the substrate, which can beused for disposing the pixel structure, but is not limited to the pixelstructure that must be provided thereon. Therefore, the substrate herecan be a base substrate used for forming a display substrate or adisplay substrate that has been already formed with a display pixelstructure.

For example, as illustrated in FIG. 2A, the substrate 100 is a flexiblesubstrate. For example, the material of the substrate 100 can includepolyimide (PI), polycarbonate (PC), polymethyl methacrylate (PMMA), andthe like, and the present embodiment is not limited thereto.

For example, as illustrated in FIG. 2A, the elongation rate of thematerial of the substrate 100 is less than 10%, that is, the elongationrate of the substrate 100 when the holes 110 are not provided is lessthan 10%, therefore, the stretchability of the substrate itself providedin this embodiment is low when the holes are not provided. However, inthis embodiment, because the substrate is provided with a plurality ofholes 110, the stretchability of the entire substrate 100 can beimproved. For example, the stretchability of the substrate 100 providedwith the holes 110 in this embodiment can be doubled as compared withthe stretchability without the holes. This embodiment is not limited tothis, for example, the stretchability can be further improved.

For example, in this embodiment, the pixel region 122 and the connectionportion 121 are integrally formed, that is, when the substrate 100provided in this embodiment is manufactured, one patterning process canbe adopted, thereby saving process steps and manufacturing difficulty.

For example, as illustrated in FIG. 2A, the area of the region where theholes 110 are provided on the substrate 100 is not greater than the areaof the non-hole region 120, that is, the area of the hole region 1100 isnot greater than the area of the non-hole region 120, so that thesubstrate can not only satisfy the stretchability in any directionparallel to the substrate, but also is not easy to fracture duringstretching.

For example, as illustrated in FIG. 2A, the plurality of pixel regions122 are arrayed in an array in a first direction (i.e., X direction) anda second direction (i.e., Y direction). The example illustrated in FIG.2A is described with the first direction and the second direction beingperpendicular to each other as an example, but is not limited thereto.

For example, the shape of the pixel region 122 in the exampleillustrated in FIG. 2A includes a rectangle, and when the shape of thepixel region 122 is rectangular, the first direction and the seconddirection are two directions parallel to adjacent sides of the pixelregion 122, respectively.

For example, as illustrated in FIG. 2A, a connection portion 121 isprovided between two adjacent pixel regions 122 in the first direction.In the second direction, a connection portion 121 is provided betweentwo adjacent pixel regions 122. In addition, in this embodiment, theconnection portion 121 is only provided between the pixel regions 122adjacent to each other in the first direction and between the pixelregions 122 adjacent to each other in the second direction. However, itis not limited to this, and the connection portion can be also disposedbetween pixel regions adjacent to each other in other directions as longas the straight line 200 with any direction parallel to the substrate100 passes through at least one hole 110.

For example, as illustrated in FIG. 2A, the connection portions 121connected to two sides of each pixel region 122 opposite to each otherin the first direction have a minimum distance greater than zerotherebetween in a third direction perpendicular to the first direction,and the third direction here is the Y direction. That is, the connectionportions 121 located on opposite sides of each pixel region 122 in thefirst direction do not overlap at all in the second direction. That is,the connection portions 121 respectively connected to the two sides ofeach pixel region 122 extending in the Y direction do not overlap at allin the Y direction.

Similarly, as illustrated in FIG. 2A, the connection portions 121connected to two sides of each pixel region 122 opposite to each otherin the second direction have a minimum distance greater than zerotherebetween in a fourth direction perpendicular to the seconddirection, and the fourth direction here is the X direction. That is,the connection portions 121 located on opposite sides of each pixelregion 122 in the second direction do not overlap at all in the firstdirection. That is, the connection portions 121 respectively connectedto the two sides of each pixel region 122 extending in the X directiondo not overlap at all in the X direction.

In this embodiment, the size and positional relationship between theconnection portion and the pixel region can ensure that the forceapplied in any direction parallel to the substrate passes through thehole region (e.g., at least one hole), so that the substrate hasstretchability in any direction.

For example, as illustrated in FIG. 2A, the plurality of connectionportions 121 are separated from each other. The above-mentioned“separated from each other” means that although the connection portions121 are connected to the pixel region 122, each two connection portions121 are spaced apart and independent of each other, so as to ensure thata force applied in any direction parallel to the substrate 100 passesthrough at least one hole 110.

For example, as illustrated in FIG. 2A, the minimum distance in thethird direction (i.e., the Y direction illustrated in FIG. 2A) and theminimum distance in the fourth direction (i.e., the X directionillustrated in FIG. 2A) of the connection portions 121 respectivelyconnected to two adjacent sides of each pixel region 122 are bothgreater than zero.

For example, as illustrated in FIG. 2A, the connection portion 121connected to the side parallel to the X direction of the pixel region122 is a first connection portion 1211, the connection portion 121connected to the side parallel to the Y direction of the pixel region122 is a second connection portion 1212, the first connection portion1211 and the second connection portion 1212 connected to the same pixelregion 122 do not overlap in the X direction, and the first connectionportion 1211 and the second connection portion 1212 do not overlap inthe Y direction, thus ensuring that the connection portions 121connected to adjacent sides of the pixel region 122 are separated fromeach other.

For example, as illustrated in FIG. 2A, the connection portion 121connected to one side of each pixel region 122 is located between thetwo end points of the side in a direction parallel to the side, that is,the first connection portion 1211 connected to the side extending in theX direction of each pixel region 122 is located between the two endpoints of the side in the X direction. Similarly, the second connectionportion 1212 connected to the side extending in the Y direction of eachpixel region 122 is located between the two end points of the side inthe Y direction. Therefore, it is further ensured that the connectionportions 121 connected to the adjacent sides of the pixel region 122 areseparated from each other.

For example, as illustrated in FIG. 2A, the plurality of connectionportions 121 each have the same shape and size, and the plurality ofpixel regions 122 each have the same shape and size, thus ensuring thatthe plurality of connection portions 121 are uniformly stressed duringthe stretching process of the substrate 100, and preventing thesubstrate 100 from being fractured due to uneven stress at a certainplace during the stretching process.

For example, in FIG. 2A, the shape of the connection portion 121 isdescribed as a rectangle. At this time, the minimum distance in thesecond direction of the connection portions 121 connected to both sidesof each pixel region 122 extending in the second direction is “a”illustrated in FIG. 2A, and similarly, the minimum distance in the firstdirection of the connection portions 121 connected to both sides of eachpixel region 122 extending in the first direction is “a′” illustrated inFIG. 2A. The substrate with the rectangular connection portions providedby this embodiment of the present disclosure can be manufactured by theexisting manufacturing process, and the process is simple.

For example, FIG. 2B is a partial schematic view showing the planarstructure a substrate according to another example of an embodiment ofthe present disclosure. As illustrated in FIG. 2B, the shapes of theplurality of connection portions 121 in this example may not be exactlythe same. For example, the shapes of the plurality of connectionportions 121 can include rectangles and trapezoids. At this time, theminimum distance in the second direction of the connection portions 121respectively connected to both sides of each pixel region 122 extendingin the second direction is “b” illustrated in FIG. 2B, and the minimumdistance in the first direction of the connection portions 121respectively connected to both sides of each pixel region 122 extendingin the first direction is “b′” illustrated in FIG. 2B. This example isnot limited to this, and the shapes of the connection portions can alsobe trapezoidal.

For example, as illustrated in FIGS. 2A and 2B, a connection portion 121can be provided between adjacent pixel regions 122. At this time, themaximum dimension in the Y direction of the connection portion 121connected to the side extending in the Y direction of the pixel region122 is less than half of the dimension in the Y direction of the pixelregion 122, so that the minimum distance in the Y direction of theconnection portion 121 respectively connected to the side extending inthe Y direction of each pixel region 122 is greater than zero.Similarly, the maximum dimension in the X direction of the connectionportion 121 connected to the side extending in the X direction of thepixel region 122 is less than half of the dimension in the X directionof the pixel region 122, so that the minimum distance in the X directionof the connection portion 121 connected to the side extending in the Xdirection of each pixel region 122 is greater than zero.

For example, the size of each pixel region 122 in the X direction can be200 to 1000 μm, and the maximum size of each connection portion 121 inthe X direction can be 20 to 160 μm. This embodiment includes but is notlimited to this.

This embodiment is not limited to this. When the maximum dimension inthe Y direction of the connection portion connected to one of the twosides extending in the Y direction of any pixel region is greater thanone half of the dimension in the Y direction of the pixel region, themaximum dimension in the Y direction of the connection portion connectedto the other of the two sides extending in the Y direction of the pixelregion is less than one half of the dimension in the Y direction of thepixel region, thereby ensuring that the minimum distance in the Ydirection between the connection portions respectively connected to thetwo sides extending in the Y direction of each pixel region is greaterthan zero. Similarly, when the maximum dimension in the X direction ofthe connection portion connected to one of the two sides extending inthe X direction of each pixel region is greater than one half of thedimension in the X direction of the pixel region, the maximum dimensionin the X direction of the connection portion connected to the other ofthe two sides extending in the X direction of each pixel region is lessthan one half of the dimension in the X direction of the pixel region,thereby ensuring that the minimum distance in the X direction betweenthe connection portions respectively connected to the two sidesextending in the X direction of each pixel region is greater than zero.

For example, FIG. 3 is a partial schematic view showing the planarstructure of a substrate according to another example of an embodimentof the present disclosure. As illustrated in FIG. 3, at least oneconnection portion 121 is provided between adjacent pixel regions 122 inat least one of the first direction and the second direction. Theexample illustrated in FIG. 3 is described with the example that thenumber of the connection portions 121 provided between adjacent pixelregions 122 is not exactly the same, but is not limited thereto. Forexample, two connection portions or more connection portions can beprovided between adjacent pixel regions.

For example, as illustrated in FIG. 3, no matter how many connectionportions 121 are provided between adjacent pixel regions 122, theminimum distance in the third direction between the connection portions121 connected to both sides opposite to each pixel region 122 in thefirst direction is greater than zero. In addition, the minimum distancein the fourth direction between the connection portions 121 connected tothe opposite sides of each pixel region 122 in the second direction isgreater than zero, so that the force applied in any direction parallelto the substrate can be ensured to pass through at least one hole, andtherefore, the substrate has stretchability in any direction.

For example, as illustrated in FIG. 3, when one side of the pixel region122 is connected to a plurality of connection portions 121, theseconnection portions 121 are separated from each other.

For example, as illustrated in FIG. 3, at least two connection portions121 are connected to two opposite and parallel sides of two adjacentpixel regions 122, and the sum of the sizes of the at least twoconnection portions 121 in the extension direction of the sidesconnected to the connection portions is smaller than the length of eachof the sides.

For example, as illustrated in FIG. 3, the plurality of connectionportions 121 each have the same shape and size.

For example, as illustrated in FIG. 3, the number of connection portions121 provided between adjacent pixel regions 122 is not exactly the same.

For example, as illustrated in FIG. 3, the number of connection portions121 provided between adjacent pixel regions 122 includes one and two.Two connection portions 121 form a connection portion pair 1213, and asingle connection portion 121 is a connection portion unit 1214 as anexample.

For example, as illustrated in FIG. 3, the connection portion pairs 1213and the connection portion units 1214 located between pixel regions 122arranged in the first direction are alternately arranged, and theconnection portion pairs 1213 and the connection portion units 1214located between pixel regions 122 arranged in the second direction arealso alternately arranged.

For example, as illustrated in FIG. 3, the pixel regions 122 arranged inthe Y direction are pixel region columns, and the connection portionpairs 1213 and the connection portion units 1214 located betweenadjacent pixel region columns are alternately arranged in the Ydirection. Similarly, the pixel regions 122 arranged in the X directionare pixel region rows, and the connection portion pairs 1213 and theconnection portion units 1214 located between adjacent pixel region rowsare also alternately arranged in the X direction, so that the substrate100 basically maintains uniform stress throughout the stretchingprocess.

For example, FIG. 4A is a partial schematic view showing the planarstructure of a substrate according to an example of another embodimentof the present disclosure. As illustrated in FIG. 4A, each pixel region122 has a hexagonal shape, and the plurality of pixel regions 122 arearrayed in an array in the first direction and the second direction. Asillustrated in FIG. 4A, when the shape of the pixel region 122 ishexagonal, the first direction (i.e., X direction) is a directionperpendicular to one side of the pixel region 122, and the seconddirection (i.e., Y direction) is a direction perpendicular to anotherside of the pixel region 122, i.e., the X direction and the Y directionare respectively directions perpendicular to two adjacent sides of thehexagon. The angle between the first direction and the second directionin this embodiment can be 120 degrees or 60 degrees. In the exampleillustrated in FIG. 4A, the angle between the first direction and thesecond direction is 120 degrees.

For example, as illustrated in FIG. 4A, a connection portion 121 isprovided between two adjacent pixel regions 122 in the first direction.In the second direction, a connection portion 121 is provided betweentwo adjacent pixel regions 122. Also, in an example of this embodiment,the connection portion 121 is only provided between pixel regions 122adjacent to each other in the first direction and between pixel regions122 adjacent to each other in the second direction.

For example, as illustrated in FIG. 4A, the connection portions 121connected to the two sides of each pixel region 122 opposite in thefirst direction have a minimum distance therebetween greater than zeroin the third direction perpendicular to the first direction, and thethird direction here is the direction perpendicular to the X direction.In addition, the connection portions 121 connected to the two sides ofeach pixel region 122 opposite in the second direction have a minimumdistance therebetween greater than zero in the fourth directionperpendicular to the second direction, the fourth direction here is thedirection perpendicular to the Y direction, so that the force applied inany direction parallel to the substrate can be ensured to pass throughat least one hole, and therefore, the substrate has stretchability inany direction. The third direction and the fourth direction are bothparallel to the substrate.

For example, as illustrated in FIG. 4A, the minimum distances in thethird direction and the fourth direction of the connection portions 121respectively connected to the two adjacent sides of each pixel region122 are greater than zero.

For example, as illustrated in FIG. 4A, the connection portion 121connected to the side extending perpendicularly to the X direction(i.e., the side extending in the third direction) of the pixel region122 is the third connection portion 1215, the connection portion 121connected to the side extending perpendicularly to the Y direction(i.e., the side extending in the fourth direction) of the pixel region122 is the fourth connection portion 1216, the third connection portion1215 and the fourth connection portion 1216 connected to the same pixelregion 122 do not overlap in the third direction, and the thirdconnection portion 1215 and the fourth connection portion 1216 connectedto the same pixel region 122 do not overlap in the fourth direction.

For example, as illustrated in FIG. 4A, there is only the hole 110between at least two adjacent pixel regions 122. For example, in adirection having an included angle of 60 degrees with both the Xdirection and the Y direction, no connection portion 121 is providedbetween adjacent pixel regions 122, and only a hole 110 is provided.

For example, the substrate illustrated in FIG. 4A has the same structurefeatures as the substrate illustrated in FIG. 2A, and will not bedescribed here again.

For example, FIG. 4B is a partial schematic view showing the planarstructure of a substrate according to another example of anotherembodiment of the present disclosure. As illustrated in FIG. 4B, what isdifferent from the example illustrated in FIG. 4A is, the connectionportion 121 in this example is not only disposed between pixel regions122 adjacent to each other in the X direction or the Y direction, butcan be further disposed between pixel regions 122 adjacent to each otherin other directions, for example, in the V direction illustrated in FIG.4B. For example, the V direction can be a direction in which theincluded angle between the X direction and the Y direction are both 60degrees, that is, the V direction is a direction along an angularbisector of the angle between the X direction and the Y direction, andthe V direction is also a direction perpendicular to one side of thehexagon. In the example illustrated in FIG. 4B, it is sufficient toensure that a straight line 200 in any direction parallel to thesubstrate 100 passes through at least one hole 110.

In the example illustrated in FIG. 4B, a connection portion 121 isprovided between any two adjacent pixel regions 122 to reduce theprobability of fracture of the substrate 100 during stretching.

It should be noted that the first direction and the second direction inthis embodiment can refer to the X direction and the Y direction, the Xdirection and the V direction, or the Y direction and the V direction,and correspondingly, the third direction and the fourth direction canrefer to the direction perpendicular to the X direction and thedirection perpendicular to the Y direction, the direction perpendicularto the X direction and the direction perpendicular to the V direction,or the direction perpendicular to the Y direction and the directionperpendicular to the V direction. The third direction and the fourthdirection are both parallel to the substrate.

For example, the substrate illustrated in FIG. 4B has the same structurefeatures as the substrate illustrated in FIG. 2A, and will not bedescribed here again.

For example, FIG. 5 is a sectional schematic view of the substrateillustrated in FIG. 2A taken along line AB. As illustrated in FIG. 5,the pixel region 122 further includes a light emitting unit 300, thatis, the substrate 100 provided by the embodiment of the presentdisclosure can be an array substrate.

For example, a red pixel, a green pixel, a blue pixel, and the like canbe disposed on the pixel region 122, and this embodiment includes but isnot limited to this.

For example, as illustrated in FIG. 5, the light emitting unit 300 caninclude a pixel electrode and a common electrode.
